This script checks if 艦これ has finally opened their server to new players.
They probably didn't and even if they did, the game itself is not that good anyway, but for those of us that are masochistic enough to want to analyze other games, but not have the patience to regularly check if the company has graced their unworthy person with the rarest of opportunities to play their game, now we can just get notified when an open server is found through the API.
If you don't know how to use this and can't figure it out on your own, probably you shouldn't use it. Go play flappy bird MMO http://flapmmo.com/ instead.
